| X231- To BY/from E/JNR.{Charles L. Jenner} c. Wor.{Arthur Wormald - General Works Manager} Hs.{Lord Ernest Hives - Chair} E/JNR.{Charles L. Jenner}1/HP.21.2.33. Bensport Tachometer Drive. We send you herewith: LeC.3376 - design for the above. This cancels our previous design LeC.3293. The reason we had to do this job again is because of the alteration to the dynamo speed and the fitting of the Phantom II machine. It will be noticed also that the direction of rotation of the tachometer drive is reversed to suit the instrument maker. E/JNR.{Charles L. Jenner} | ||
